Some mountain glaciers in both the Northern and Southern Hemispheres advanced in late Atlantic and early sub‐Boreal time, between about 5,200 and 4,600 radiocarbon years ago, and several in the Southern Hemisphere reached their greatest post‐glacial extents. This suggests that the cool phase was as severe as at the start of the sub‐Atlantic (ca. 2,800 radiocarbon years ago), but many botanists believe that the fluctuation was weak. Much botanical evidence indicates that the cool phase was followed by renewed warmth and divided the Hypsithermal Interval into two parts of unequal length.
